For whatever reason some people still think steel case ammo isn't reliable, but I've had no issues with Tul (or Wolf). Went through about 800 rounds of Tul, no duds. Fired from a Canik TP9sfx and CZ Shadow 2. Only reason I didn't buy more was the Wolf Brand was a little cheaper in bulk.

If you are a high volume shooter, this is the ammo for you. 9mm ammo rounds have a Full Metal Jacket bullet and are noncorrosive, with smooth-cycling. They have cylinder-shaped steel case with a with non-projecting flange and polymer-coating.
